Okay, I have a feeling this is a pretty easy problem to solve, the only trouble is, my professor worded it really weirdly, so I only have half an idea of what it's asking. Any ideas? ----------- Let the Electric field be E at a point P near a conductiong material. Because of electrostatic induction, the force on a charge q at P will not yield E. Show, however, that the average of the fields of two equal and opposite charges +q and -q gives the correct value: E=(Fq+-Fq-)/2q. ------------ From what I can gather, it's asking me to prove the average E field of a dipole is that. Thanks. EDIT: Nevermind, I just figured it out.
